Abstract

There is a popular notion that the Paddlefish (Polyodon spathula) uses its paddle or snout as an organ of excavation in its search for food. Examination and consideration of the composition and texture of this organ ought to lead one to question the correctness of the popular opinion. The snout or rostrum of the common sturgeons may well be an organ of excavation, armed and protected as it is with bony plates, but the rostrum of the paddlefish is covered with a soft naked skin. Stockard (1907) has given us a very thorough and enlightening account of the habits of this fish.
